Snails in Soft Water Tanks
I've already posted this on TFK and haven't received a response yet aside from someone stating they would also like to know, so I figured I would give this forum a shot (and if no one here knows either, perhaps a snail-specific forum).
Lately I've been reading up on water conditions, specifically KH, GH, and pH; currently I only have Bettas and I haven't done anything to alter these levels in their tanks, but I would like to eventually set them up in larger tanks and try to give them as ideal of water conditions for their species as I can (i.e. soft water). I'd also like to eventually set up a large tank with some Glofish who, incidentally, also do best in soft water -- so yet another soft water tank.
Now, I already have Mystery Snails, which I know do best in hard water due to their calcium needs (that's the reason I've seen mentioned, at least), so I'm trying to figure out if I could keep them in soft water tanks or if they would be best off in "their own" hard water tank. I haven't found anything that definitively answers my question (that I can see).
If I keep the pH stable and in the proper range for the snails, can I get away with keeping them in soft water but with a calcium-rich diet?
I'm thinking primarily by way of dark, leafy greens if that makes a difference.
Most of what I'm seeing seems to be more focused on making the water harder, which isn't what I'm looking for. Mostly looking for opinions and/or experience -- if it's not advisable then I can figure something out (I've kind of toyed with the idea of a Guppy tank, so perhaps I could put them in there or in their own tank if I can't do the Guppies). Regardless, this isn't an immediate thing. I still have a lot of work to do as far as understanding and figuring out these three aspects of water quality before I start messing around with them, plus we may very well be moving before too long.
I would really appreciate someone who has a good idea regarding the efficacy of this idea answering, because I've seen it indicated a few times that pH is the more important of the two, and I'm not sure if that means one could get away with soft water with snails.
